"I don't know if they were extremely sudden or if something (led) up to it," Mackinday replied.

Mackinday testified a day earlier that Koppenhaver beat her several times and raped her in the months before the August 2014 attack that injured her and Thomas. Earlier that year, she said she suffered a black eye, cut nose, a bite mark on her chin and a chipped tooth in an attack in a vehicle he was driving.

Thomas testified that Koppenhaver broke his nose and dislocated his shoulder before releasing him with a warning that if he went to the police, Koppenhaver would hurt him.

Mackinday said she escaped bleeding from her home, when she thought Koppenhaver was fetching a knife to kill her. She said he broke a knife during another attack that left her with shredded hair, cuts on her scalp, a broken nose, missing teeth, fractured eye socket, leg injuries and a lacerated liver.

"No way I could physically overpower him," Mackinday said, "and if I were to fight back, it would be 10 times worse."

Leiderman has not denied that the August 2014 fight took place. But he told the jury that Mackinday had rape fantasies and invited Koppenhaver to surprise her, and he cast the relationship as a mutual co-dependence that inevitably exploded into violence.

Koppenhaver has pleaded not guilty to attempted murder, kidnapping, battery, sexual assault and coercion that could get him life in prison without parole in incidents before and during an August 2014 attack on Mackinday and Thomas.
